Answer:
It takes the Dolphin 2 hours for swimming 40 miles. The penguin takes 8 hours and the swordfish will take 2/3 of an hour, which is 40 minutes to travel 40 miles.
Step-by-step explanation:
Given :
The bottlenose dolphin travels 40 miles in 2 hours. Or it takes 20 miles in 1 hour.
Now, dividing the distance by unit rate given in the question:
40/20=2 hours
40/5=8 hours
40÷60= 2/3 hour
Therefore,
- the dolphin takes 2 hours for swimming 40 miles.
- the penguin takes 8 hours
- the swordfish takes 2/3 rd of an hour
